Incidence and Risk Factors of Urinary Retention in Acute Ischemic Stroke Patients: A Retrospective Study.

Abstract

Objectives: This study aimed to evaluate the incidence and risk factors of urinary retention in acute ischemic stroke (AIS) patients.

Materials and methods: A total of 993 patients diagnosed with AIS were analyzed retrospectively. According to the incidence of urinary retention, these patients were divided into the urinary retention group and the nonurinary retention group. The incidence of urinary retention after AIS was analyzed. Univariate analysis and binary logistic regression analysis were performed to screen the independent risk factors for urinary retention after AIS.

Results: The incidence of urinary retention in AIS patients was 10.98% (109/993). According to the results of the univariate analysis, age (P<0.01), sex (P=0.020), National Institutes of Health Stroke Scale (NIHSS) <10 (P<0.01), Barthel Index (BI) <40 (P<0.01), multiple cerebral infarction (P=0.002), manual muscle test (MMT) (P<0.01), urinary tract infection (UTI) (P<0.01), and benign prostate hyperplasia (BPH) (P<0.01) were significantly correlated with urinary retention incidence. The binary logistic regression analysis revealed that female (OR: 1.954, 95% CI: 1.065-3.587), BI <40 (OR: 24.067, 95% CI: 11.652-49.713), UTI (OR: 8.214, 95% CI: 3.714-18.169), and BPH (OR: 11.342, 95% CI: 5.460-12.560) were independent risk factors for urinary retention after AIS.

Conclusions: The incidence of urinary retention in AIS patients was 10.98%. BI <40, UTI, and BPH were identified as risk factors for poststroke urinary retention. In addition, being female constituted another risk factor for urinary retention, requiring further study.
